如何在Windows中获取当前login用户的域名？

请参阅如何在Windows NT，Windows 2000或Windows XP上检索当前用户和域名 。

例：

#define UNICODE #define _UNICODE #include <windows.h> #include <tchar.h> BOOL GetCurrentUserAndDomain(PTSTR szUser, PDWORD pcchUser, PTSTR szDomain, PDWORD pcchDomain) { BOOL fSuccess = FALSE; HANDLE hToken = NULL; PTOKEN_USER ptiUser = NULL; DWORD cbti = 0; SID_NAME_USE snu; __try { // Get the calling thread's access token. if (!OpenThreadToken(GetCurrentThread(), TOKEN_QUERY, TRUE, &hToken)) { if (GetLastError() != ERROR_NO_TOKEN) __leave; // Retry against process token if no thread token exists. if (!OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY, &hToken)) __leave; } // Obtain the size of the user information in the token. if (GetTokenInformation(hToken, TokenUser, NULL, 0, &cbti)) { // Call should have failed due to zero-length buffer. __leave; } else { // Call should have failed due to zero-length buffer. if (GetLastError() != ERROR_INSUFFICIENT_BUFFER) __leave; } // Allocate buffer for user information in the token. ptiUser = (PTOKEN_USER) HeapAlloc(GetProcessHeap(), 0, cbti); if (!ptiUser) __leave; // Retrieve the user information from the token. if (!GetTokenInformation(hToken, TokenUser, ptiUser, cbti, &cbti)) __leave; // Retrieve user name and domain name based on user's SID. if (!LookupAccountSid(NULL, ptiUser->User.Sid, szUser, pcchUser, szDomain, pcchDomain, &snu)) __leave; fSuccess = TRUE; } __finally { // Free resources. if (hToken) CloseHandle(hToken); if (ptiUser) HeapFree(GetProcessHeap(), 0, ptiUser); } return fSuccess; } int main() { TCHAR user[1024], domain[1024]; DWORD chUser = sizeof(user), chDomain = sizeof(domain); if (GetCurrentUserAndDomain(user, &chUser, domain, &chDomain)) { _tprintf(TEXT("user:%s\ndomain:%s\n"), user, domain); } } 

输出在我的情况下：

 user:dlaru_000 domain:IKH-WIN81 

请注意，您必须将程序链接到advapi32.lib。
